Device for fixing in a fluid tight manner a through tube in a dome-shaped wall of a component of a nuclear reactor

摘要

The through tubes (8) are a shrink-fit in through openings in the dome- shaped wall (2). One end (8a) of the tubes which projects from the convex surface of the wall (2) is closed in a fluidtight manner and a wall (18) carrying an electron gun (19) is mounted and fixed in a fluidtight manner on the dome-shaped wall (2) so as to define a fluidtight chamber (24). A low pressure is created in the fluidtight chamber (24) and the electron beam firing axis (19a) of the electron gun (19) is directed along a generatrix of the joint region between a through tube (8) and a through opening in the dome-shaped wall (2). The joint region is scanned by the electron beam by displacing the electron gun (19) in rotation about the axis of the through tube (8). The invention is in particular applicable to the welding of through adapters (8) of a vessel cover (2) of a pressurized water nuclear reactor.
